To alt whom it may concern.-

Be it known that I, FRANK P. SHEPARD, a citizen of the United States, residing at Edmond, in the county of Oklahoma and Territor of Oklahoma, have invented certain new an useful Improvements in Weighing Attachments for Wagons, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of the invention is to produce an attachment for wagons for wei hing the contents of the wagon-bed in whic the bed may be freed from frictional contact with the holsters and bolster-standards durin the operation of weighing, in which there w1 l be less tension or cramping between the bearings as the wagon-bed is raised from the bolster for weighing, which shall have fewer bearin s other than the common pinandclevis earings, which shall be simple and easy to construct, and which will more accurately indicate the weight of the contents of the wagon-bed than devices of this class heretofore produced.

Other objects and advantages of the invention will bc set forth in the ensuing description.

Referring to the accompanying drawings, Figure 1 is a left-hand side elevation o a wagon with the improved attachment in place and in position for weighing. Fig. 2 is an inverted plan view showing the wagonbed and bolsters with the improved attachment in place. Fig. 3 is a left-hand side elevation of a portion of a wagon-bed, on larger scale, showing an ioperatlvc position of one of the levers employed. `F ig. 4 is a perspective view of the end of a supportin cross-bar for thc bed. Fig. 5 is a sectiona view taken on the line 5 5, Fig. 1. Fig. 6 is a view similar to Fig.`5, showing the position of the bolster-standards as the wagon-bed is supended for weighing.

. {cferring to the severaligures, in all of which like characters of reference designate like parts, the bolster-standards 5 are mounted pivotally upon the bolsters 6 and adapted to swing outward clear of the wagon-bed as the latter is suspended for weighing. Each standard is composed of two mating L- shaped portions 5b, which are rivet toget er at their upper ends and spread apart at their lower ends to straddle the bolster 6. A pivot-bolt 7 asses through the lower or pivot ends of the portions 5b and through the holsters 6 at the angle or corner of t e standards, and the lower or horizontal portions 5" of said standards extend in along the holsters under the bottom 8b of the Wagonbed 8. The inner ends of the Vhoriontal arms 5c of each standard are provided with slots .5d concentric to the ivot-bolt 7, and a bolt 9 asses through sai slots and through the boister to limit the upward swinging of said arms and the outward swinging of the standards 5'. The slots 5d are made of such length as to allow the standards 5 to swing away from the wagon-bed 8 the roper distance for a safe clearancesay or three-fourths of an inch at their lpper ends-and since the portion of said stan ards near the pivot-bolt 7 cannot move the distance required to properly clear the bed 8 that portion is sha ed, as at 5, to clear said bed at all timos. Xs the 'wagon-bed is raised up clear of the lolster by means later described, it allows the inner ends of the horizontal arms 5 to raise up, and thus allows the standards to swing outward in obedience to means hereinafter described, and as said bed is again lowered onto the holsters it forces said arms back down and draws the standards 5 in forcibly against said bed.

Each standard 5 supports a lcv er 10! which extends through an opening 5 therein, and said lever is ulcrumed in a clevis 11, susended from a hook 5lz on said standard. Iwo ssuiporting cross-bars l2 extend across unfher the Wagon-bed 8, one in front' of the front bolgler Gand the other behind the rear bolster, the ends of the front bar being suspended firm the shorter arms of the front air of l. vors 10 and the ends of the rear bar irom thi shorter arms of the rear air of levers. 'f1 e connection between eac lever 10 and il s l ar 12 is formed by the common clevis 13, pivoted to said lever by the common knife-edge 1pivot-pin 14, and a rod 13b, which is welded integrally to said clevis, said rod extending down through an open-ended slot 12b in the bar 12 and having a Washer 15 and screw-nut 16 for adjustment of its len th. Each rod 13b is retained removably wit in its slot 12b by an inverted-cone-shaped memve-eighths IOO `arm 19d, radially o ber 17, mounted slidably on said rod and adapted to rest in a correspondingly-shaped depression 12, formed in the upper portieri of said slot, as shown in Fig. 4, and said member 17 is held vieldably into engagement with said depression by a helical spring 18, mounted on said rod and having bearing against the elevis 13 at its up er end. When the wagon-bed 8 rests upon t e holsters 6, the levers 1() assume the position shown in Fig. 3, the bed bein raised clear of the holsters for weighing by rawin said levers down to horizontaelposition, an since the levers are suspend from the standards 5 at points outwardly of a vertical line :n :n passing through the pivot-bolt 7 the weight or action of said levers throws said standards away from the bed 8 into the position shown in Fig. 6, as previously described. When the levers 10 are drawn down into horizontal position f or suspending the bed 8 and weighing, the longer arm of each is connected with and adapted to impart revolving motion to a rock-shaft 19, mounted transversely under the central portion of said bed. This rockshaft 19 is mounted in antifriction-bearings 20, secured to the under faces of the footsteps 21 of the bed, said shaft being provided at one end with an arm 19h, to which the levers 10 at its side of the wagon are operatively connected, and at the other end with a like arm 19, to which the levers at that side are connected. The operative connection between the leverslO and arms 19b and 19c just described com rises the common clevises pivoted to sais levers and arms by the usual knife-edge pin, and the rods-23, which hook permanently into the lever-clevises and removably into the arm-clevises. A third posing the arms 19b and 19, extends from t e rock-shaft 19, and said arm is operatively connected with a common wel h-beam 24, mounted above-on the side of t e bed 8, the connection between said arm and beam being made in the same manner as that between the arms 19b and 19c and the levers 10. This beam 24 is fulcrumed in the usual clevis 25, which is suspended permanently from an overhanging support 26, said support being removabl inserted in a supprting-socket 26, rivete to the side of the d 8. A loop 28 for limiting the balancing movements of the beam 24 is riveted to the side of the bed 8, and said beam is provided vvith the usual weighing-poise 29 and balancing-poise 30. The arms of the levers 1() and the arms of the rock-shaft 19 are made of such proportionate length and the beam 24 so graduated as to accurately indi- (atp the weight of` anything placed into the In order that the wagon-bed 8 may move freely up and down and not swing excessively when suspended by the levers 10, a stay-rod 31 is employed to limit the movements of said bed in a forc-and-aft direction, and two like rods 32 are used to limit its movements in a lateral direction. The rod 31 has one oi' its ends secured ivotally to an eye 33, which is screwed into tie rear face of the rear bolster 6, and the opposite end of said rod is secured pivotally to a lug 34, bolted to the under face of the rear cross-sill 35 of the bed. One of the rods 32 has one of its ends pivoted to an eye 36, screwed into the rear face of the rear bolster 6 and its opposite end pivoted to a lug 37, bolted to the crossbar 12, while the other rod forms a like connection between the front bolster 6 and the front cross-bar 12. Each of these rods 31 and 32 should be aproximately horizontal when the wagon-be 1s suspended for weighing, and when thus arranged they will prevent the bed from moving excessively or swinging into contact wit the standards 5 without exerting any force verticall on said bed.

ln or( er to lower the bed 8 onto the bolsters 6 and relieve the strain upon the levers, standards, and bearings while the wagon is used, the connecting-rods 23 are unhooked from the arms 19b and 19c of the rock-shaft 19, and said levers are allowed to swing up into the position shown in Fig. 3. en in this inoperative position, each lever 10 rests in a supportinghook 38, riveted to the side of the wagon-bed 8, and said levers are re tained in said hooks by the action of the springs 18 on the rods 13b, said springs holding said levers up affainst the u per edges of the o enings 5r of tthe standar s and relieving t 1e wearing strain u on the bearings. The weigh-beam 24 may )e left suspended from its supporting-arm 26 or it may be removed therefrom and placed into the wagonbed.

By employing the rock-shait 19 and mounting it transversely under the bed 8 to form the operative connection between parts on opposite sides of said bed said connection may at all times be left in its place without being in the way, noticeable, or liable to injury, and as the action of all parts operatively connected with said shaft is upward thereon it will dro away from its bearing-surfaces when said arts are disenga ed and avoid wear from tlie movements oft e wa on. By suspending the wagon-bed from t e levers 10 instead of supporting it upon bearings .placed between it and the bolsters 6 the action of' the levers and bearin s will be less liable to be interfered with y tension or cramping influences when the distance between the holsters 6 is not and cannot be accuratel spaced and controlled.

It will e seen that the device is simple and easy the parts allows the use of more o the common pin-and-clevis bearings, and that the ob'eets of the invention are fully attained.

he foregoing being a full, clear, and exact to construct, that the arran ement of IOS description of the inventing-what I claim, and desire to secure by Letters Patent, is-
